window on account of water accumulation.

therebeneath is entirely done away with, in which case the underside of doors and windows are protected or insulated against the elements.

Another object is to provide an improved fitting joint between a swingingly mounted object and a stationary object in which the cooperating parts are adapted to resiliently engage each other, thereby providing a water proof joint between said objects.

Other and further objects will appear'in the specification and be specifically pointed out in the appended claims, reference being had to the accompanying drawings exemed to swing inwardly, said horizontal rail being in vertical alinement with the window sill 2 when said rail portion of the window is in its closed position as shown in Fig. 1. Secured to the upper surface of the window sill 2, by nails or screws 3 is a stationarily mounted metal engaging strip 4, said strip 4 preferably having a downwardly inclined surface 5 formed thereon, said strip 4 also having a horizontally arranged inwardly extending P02131011 .6 formed on the top thereof;

Secured to the lower end of the outside surface 7 of the'horizontal window rail 1 is a weather strip 8, said weather strip having a downwardly and outwardly inclined water shedding portion 9 formed thereon. Formed in the top of said weather strip 8 is a horizontally arranged inwardly bent portion 10, said inwardly bent portion being seated in an upwardly I inclined recess 11 which is formed in the outside surface 7 of the horizontal window rail 1. 1

Formed in said weather strip 8, adjacent the lower end of the shedding portion 9 is an inverted groove 12.

This improved weather strip is preferably made of pliable sheet metal, and leading from the inverted groove 12 isv formed a horizontal portion 13 which is adapted to be engaged against the underside 14; of the horizontal window rail 1, and there being nails 15 passing throughthe horizontal portion 13 so as to hold said horizontal portion firmly against the underside 14 of the window rail 1. Leading from the horizontal portion 13 is a downwardly. inclined portion 16 which extends inwardly, the end of said portion 16 being bent outwardly so as to form a groove 17. Formed on the end of the horizontal rail 1 of the windowis a downwardly pending offset portion 18. I

As afore stated, this improved weather strip isapplicable to swin ingly mounted or casement windows. hose windows, which swing similar to doors are swung in jllZtELPOSltlOIl above the window sill and in such instances there is just enough clearance given between the window sill and the lower edge or underside of the window to allow for the swing thereof. Water from rain storms generally accumulates between the underside of the window and the window sill, and is held there for a while by capillary attraction until it is drawn up on account of being absorbed by the underside of the window. This therefore causes the underside of the window to swell and jam against the window sill. This improved weather strip is therefore adapted to' eliminate the aforesaid swelling of the lower portion of the window and from the afore said description, it is readily seen that the underside 14 of the window is insulated by the portions 13 and 16 of the weather strip 8. In the construction of -the weather strip 8, the inclined portion 16 thereof is given a greater incline than is shown in its present position so that when the window is swung Specification of Letters Patent. Patented J 1111 15,1920.

away from the window sill, the inclined portion 16 will have a tendency to swing downwardly on account of the metal having a certain amount of resiliency contained.

therein, and when the window is moved into a. closed position, the undersideof the inclined portion16 of the weather strip will engage and ride on .top of the inwardly extending portion 6 of the stationary engaging inwardly extending portion 6 of the window sill or stationary strip 4.

Attention is also called to the embedding of the inwardly bent portion 10 in the recess 11 which will prevent water from going behind the weather strip and as the water travels down the water shedding portion 9 of the weather strip, the water will drip from the dripping portion 19 which is formed adjacent the inverted groove 12. This inverted groove 12 is adapted to prevent the water from jumping or traveling across to the horizontal portion 13 of said weather strip.

To further secure the front portion of the weather strip 8 to the window, nails 20 are driven through the upper portion thereof ad'acent the inwardly bent portion 10-.

Re erring to Fig. 2 of the drawings which shows this improved device applied ,to the underside and front surface of a door, the door carried weather strip 21 is identical with the window carried weather strip 8 as before described in which said weather strip 21 has a downwardly and inwardly inclined portion 22 formed thereon which is similar to the inclined portion 16 of the weather strip 8, and there being a longitudinal pocket 23 formed at the terminus of the inclined portion 22. This inclined portion 22.is adapted to resiliently engage the inner edge 24 of'the door sill wearplate 25 which is mounted on the door sill 26.

In a weather strip of this improved character in which there are only two pieces of sheet metal required for its manufacture, it is readily seen that a practicable, durable and economical weather strip can be provided.

What I claim is: 1. A weather strip for a swinging closure constructed of a single piece of sheet metal comprising ,a downwardly and outwardly inclining portion and a horizontally arranged portion, said downwardly inclining portion adapted to be engaged against the outside vertical portion of the swinging closure, said horizontal portion adapted to be secured against-the underside of the swinging closure, and there being an inverted groove formed by the upwardly bending of the metal between the inclining portion and the horizontal portion, and a rearwardly extending portion inclining downwardly from said horizontal portion.

2. A weather strip for. a swinging closure constructed. of a single piece of sheet metal having a portion which is adapted to be engaged against the outside vertical portion.

of the closure adjacent the bottom, said portion inclining downwardly and away from the closure adjacent the bottom, thereby forming a weather drip, and there being an extending inverted groove formed by the bending of the metal upwardly and downwardly from the weather drip portion, in which the groove-is formed within the confines of the inclining portion, and there be ing a horizontal portion extending rearewardly from said groove engaging against the underside of the sash, and extending rearwardly from said horizontal portion is a downwardly inclining portion forming a re siliently engaging member for engagement with a part with which it is adapted to co-
